Size and weight
 
Just noticed the size and weight of the solar panel on the Harbor Freight web page...

Overall dimensions: 35-7/16" L x 11-7/16" W x 1" thick
Shipping Weight: 13.80 lb.

It's a whole lot bigger than the one the Aussie bloke put on his wing tip!

Reverse Polarity

...some reviewers indicate it is easy to connect the solar plug and battery plug to the wrong connectors (polarity reversed) and fry the regulator.
Solving this issue is as simple as selecting a "keyed" connector which cannot be plugged in backwards. Yes, alligator clips were mentioned, but if I go to that trouble, I'd prefer to set up a permanent installation.

For what it's worth.... :)
